On Track Visually?

By David Morse, 19 September 2023

A chance encounter with navigation officers during ship visits as part of the recent Halifax Fleet week,
brought this old adage back to mind. Apart from the expected disparaging remarks about “old-timers”
and reliance on paper charts, there was a surprising blind spot about issues surrounding the exclusive

Explorer aground off Greenland – navigation error?

Navies are required to operate wherever sent – regardless of the state of accurate charting in the
region; regardless of the accuracy of the space-based systems or their availability in times of conflict.
Accounts of GPS spoofing and jamming in the current Ukrainian conflict should be carefully examined.

A chance encounter and a limited data set perhaps, but the “on-line” generation of sailors might find
this well researched examination of electronic navigation worthwhile
